FIELD OF THE INVENTION

The present invention relates to cell penetrating peptides derived fromhuman telomerase reverse transcriptase (hTERT) enzyme, conjugates of thecell penetrating peptides, active ingredients, and compositionscomprising the conjugate.

BACKGROUND

Although Low-molecular weight substances, nucleic acids, proteins,nano-particles, etc, have great potentials as therapeutic substances ata molecular level, their uses are limited due to the incompetence topenetrate into tissues and cell membrane. The development of a system todeliver such substances into the cell has been the active area ofresearch over the last two decades. transport the substances inside thecell has been a conversation topic in a treatment of molecular method.Low-molecular weight substances, nucleic acids or nano-particles weretransported inside the cell by several reagents, electroporation orheatshock. However, it was difficult to find an adequate method ofdelivery of proteins inside the cell without disrupting the activity andintegrity of proteins. In 1980s, in the research conducted on studyingthe cell penetrating capacity of HIV, it was found that HIV-TAT proteinconsisting of specific 11 amino acids play an important role in aprocess of transportation inside the cell. Thus, in 1990s, studies onfinding the right method of transporting proteins inside the cell hasbeen the intense area of research.

Telomere is known as a repetitive sequence of genetic material found atthe ends of chromosomes that prevent chromosomes from damage or mergingonto other chromosomes. The length of the telomere is shortened at eachcell division, and after a certain number of cell division, the telomerelength is extremely shortened to the extent in which the cell stopsdividing and dies. On the other hand, the elongation of telomeres isknown to extend the life span of a cell. For an example, cancer cellsexcrete an enzyme called telomerase, which prevents shortening oftelomeres, thus resulting in proliferation of cancer cells.

DETAILED DESCRIPTION OF THE INVENTION

Proteins, Nucleic acids, Peptides or virus etc. have big potentials tobe used as therapeutic substances. However, their uses are limitedbecause they cannot penetrate tissues and cell membrane due to molecularlevel sizes. Although, the size of molecules is small, they cannotpenetrate lipid-bilayer due to structure or characteristics of themolecules. Thus, through the use of electroporation, heat shock, etc.,there were attempts to transport proteins, nucleic acids, peptides orviruses inside the cell; it was difficult to transfer those withoutneither damaging cell membrane nor keeping the active states of abovemolecules. There have been many studies conducted since TAT(Trans-Activating Transcriptional activator) protein derived from HIV(Human Immuno-deficiency Virus) has shown to work as cell penetratingpeptide which can transport huge active substances inside the cell.Specifically, there have been studies conducted about substances thatcan transport huge molecules such as proteins, nucleic acids, peptidesor virus inside the cell without causing any toxicity, unlike TATprotein which causes toxicity inside the cell. Therefore, the presentinvention was completed as present inventors have found that peptidesderived from telomerase have outstanding efficacy as cell penetratingpeptide without a noticeable toxicity.

Moreover, the peptidesdisclosed in the present invention can include a peptide comprising anyone amino sequence among SEQ ID NO: 1 to SEQ ID NO: 156 or itsfragments, and a peptide with more than 1 transformed amino acid, morethan 2 transformed amino acid, more than 3 transformed amino acid, morethan 4 transformed amino acid, more than 5 transformed amino acid, morethan 6 transformed amino acid, or more than 7 transformed amino acid.

In one embodiment of the present invention, changes in amino acidsequence belong to the modification of peptide's physical and chemicalcharacteristics. For example, amino acid transformation can be performedby improving thermal stability of the peptide, altering substratespecificity, and changing the optimal pH.

The term “amino acid” herein includes not only the 22 standard aminoacids that are naturally integrated into peptide but also the D-isomersand transformed amino acids. Therefore, in a specific embodiment of thepresent invention, a peptide herein includes a peptide having D-aminoacids. On the other hand, a peptide may include non-standard amino acidssuch as those that have been post-translationally modified. Examples ofpost-translational modification include phosphorylation, glycosylation,acylation (including acetylation, myristorylation, plamitoylation),alkylation, carboxylation, hydroxylation, glycation, biotinylation,ubiquitinylation, transformation in chemical properties (e.g. β-removingdeimidation, deamidation) and structural transformation (e.g. formationof disulfide bridge). Also, changes of amino acids are included and thechanges of amino acids occur due to chemical reaction during thecombination process with crosslinkers for formation of a peptideconjugate.

A peptide disclosed herein may be a wild-type peptide that has beenidentified and isolated from natural sources. On the other hand, whencompared to peptide fragments of any one amino sequence among SEQ ID NO:1 to SEQ ID NO: 156, the peptides disclosed herein may be artificialmutants that comprise one or more substituted, deleted and/or insertedamino acids. Amino acid alteration in wild-type polypeptide—not only inartificial mutants—comprises conservative substitution of amino acidsthat do not influence protein folding and or activation. Examples ofconservative substitution belong to the group consisting of basic aminoacids (arginine, lysine and histidine), acidic amino acids (glutamicacid and aspartic acid), polar amino acids (glutamine and asparagines),hydrophobic amino acids (leucine, isoleucine, valine and methionine),aromatic amino acids (phenylalanine, tryptophan and tyrosine), and smallamino acids (glycine, alanine, serine, and threonine). The amino acidsubstitutions that do not generally alter the specific activity areknown in the art of the present invention. Most common occurredalteration are Ala/Ser, Val/Ile, Asp/Glu, Thr/Ser, Ala/Gly, Ala/Thr,Ser/Asn, Ala/Val, Ser/Gly, Tyr/Phe, Ala/Pro, Lys/Arg, Asp/Asn, Leu/Ile,Leu/Val, Ala/Glu, Asp/Gly, and the opposite alterations. Another exampleof conservative substitutions are shown in the following table 2.

The substantial transformation of the biological properties of peptidesare performed by selecting significantly different substitution in thefollowing efficacies: (a) the efficacy in maintaining the structure ofthe polypeptide backbone in the area of substitution, such as sheet orhelical three-dimensional structures, (b) the efficacy in maintainingelectrical charge or hydrophobicity of the molecule in the target area,or (c) the efficacy of maintaining the bulk of the side chain. Naturalresidues are divided into groups by general side chain properties as thefollowing:

-   (1) hydrophobicity: Norleucine, met, ala, val, leu, ile;-   (2) neutral hydrophilicity: cys, ser, thr;-   (3) acidity: asp, glu;-   (4) basicity: asn, gln, his, lys arg;-   (5) residue that affects chain orientation: gly, pro; and-   (6) aromaticity: trn, tyr, phe.

Non-conservative substitutions may be performed by exchanging a memberof the above classes to different classes. Any cystein residues that arenot related in maintaining the proper three-dimensional structure of thepeptide can typically be substituted into serine, thus increasing theoxidative stability of the molecule and preventing impropercrosslinkage. Conversely, improvement of stability can be achieved byadding cysteine bond(s) to the peptide.

Altered types of amino acids variants of peptides are those thatantibody glycosylation pattern changed. The term “change” herein relatesto deletion of at least one carbohydrate residues that are found in apeptide and/or addition of at least one glycosylated residues that donot exist within a peptide

Glycosylation in peptides are typically N-connected or O-connected. Theterm “N-connected” herein relates to that carbohydrate residues areattached to the side chain of asparagine residues. As tripeptidesequences, asparagine-X-serine and asparagine-X-threonine (where the Xis any amino acid except proline) are the recognition sequence forattaching carbohydrate residue enzymatically to the side chain ofasparagine. Therefore, with the presence of one of these tripeptidesequences in a polypeptide, the potential glycosylation sites arecreated. “O-connected glycosylation” means attaching one of sugarN-acetylgalactosamine, galactose, or xylose to hydroxyl amino acids. Thehydroxyl amino acids are most typically serine or threonine, but5-hydroxyproline or 5-hydroxylysine can be used.

Addition of glycosylation site to a peptide is conveniently performed bychanging amino acid sequence to contain tripeptide sequence mentionedabove (for N-linked glycosylation sites). These changes may be made byaddition of at least one serine or theronine residues to the firstantibody sequence, or by substitution with those residues (for O-linkedglycosylation sites).

In one embodiment of the present invention, a cargo can be directlycombined with the peptide. In another embodiment of the presentinvention, a cargo can be combined to the peptide via various types ofbonds such as covalent or non-covalent bonds. A cargo, for example, canbe combined to the N-terminal or C-terminal of the peptide in oneembodiment of the present invention. For example, a cargo can be bondedto the peptide by disulfide bonds or covalent bonds. The covalent bondsare the bonds that a cargo can be bonded to a-amine of N-terminalglutamate, or amine of C-terminal Lysine residues. Also, a peptide and acargo can be combined via a non-covalent bond, which can have either apeptide or a cargo can encapsulate the other as a capsule form.

EXAMPLE 1 Synthesis of Peptide

The peptides of SEQ ID NO: 1 to SEQ ID NO: 156 were synthesizedaccording to the existing method of solid phase peptide synthesis. Indetail, the peptides were synthesized by coupling each amino acid fromC-terminus through Fmoc solid phase peptide synthesis, SPPS, usingASP48S (Peptron, Inc., Daejeon ROK). Those peptides with their firstamino acid at the C-terminus being attached to resin were used asfollows:

-   NH₂-Lys(Boc)-2-chloro-Trityl Resin-   NH₂-Ala-2-chloro-Trityl Resin-   NH₂-Arg(Pbf)-2-chloro-Trityl Resin

All the amino acid materials to synthesize the peptide were protected byFmoc at the N-terminus, and the amino acid residues were protected byTrt, Boc, t-Bu (t-butylester), Pbf (2,2,4,6,7-pentamethyldihydro-benzofuran-5-sulfonyl) that can be dissolved in acid. Such as:

-   Fmoc-Ala-OH, Fmoc-Arg(Pbf)-OH, Fmoc-Glu(OtBu)-OH, Fmoc-Pro-OH,    Fmoc-Leu-OH, Fmoc-Ile-OH, Fmoc-Phe-OH, Fmoc-Ser(tBu)-OH,    Fmoc-Thr(tBu)-OH, Fmoc-Lys(Boc)-OH, Fmoc-Gln(Trt)-OH,    Fmoc-Trp(Boc)-OH, Fmoc-Met-OH, Fmoc-Asn(Trt)-OH, Fmoc-Tyr(tBu)-OH,    Fmoc-Ahx-OH, Trt-Mercaptoacetic acid.

HBTU [2-(1H-Benzotriazole-1-yl)-1,1,3,3-tetamethylaminiumhexafluorophosphate]/HOBt [N-Hydroxybenzotriazole]/NMM[4-Methylmorpholine] were used as the coupling reagents. In 20% of DMF,piperidine was used to remove Fmoc. In order to remove the protectionfrom residue or to separate the synthesized peptide from Resin, cleavagecocktail [TFA (trifluoroacetic acid)/TIS (triisopropylsilane)/EDT(ethanedithiol)/H₂O=92.5/2.5/2.5/2.5] was used.

Peptides were synthesized by using the solid phase scaffold by addingeach amino acid with the sequential proesses as follow; amino acidprotection, coupling reaction, washing, and deprotection. After cuttingoff the synthecized peptide from the resin, it was purified by HPLC andverify for synthesis by MS, and then freeze-dried.

Specific peptide synthesis process is described by the following withexample of Pep1 of SEQ ID NO: 164(EARPALLTSRLRFIPK).

1) Coupling

The amino acid (8 equivalent) protected withNH₂-Lys(Boc)-2-chloro-Trityl Resin was melted in coupling agent HBTU (8equiv.)/HOBt (8 equiv.)/NMM (16 equiv.), and upon addition of DMF, thereaction mixture was incubated at room temperature for 2 hours, thenwashed sequentially with DMF, MeOH, and DMF.

2) Fmoc Deprotection

Following the addition of 20% piperidine in DMF, the reaction mixturewas incubated at room temperature for 5 minutes 2 times, then washedsequentially with DMF, MeOH, and DMF.

3) Make the Basic Framework of Peptide by Repeating Reactions 1 and 2Repeatedly.

4) Cleavage: Add Cleavage Cocktail to the Completely Synthesized Peptideand Separate the Peptide From the Resin.

5) Add pre-chilled diethyl ether into the mixture, and then centrifugethe reaction mixture to precipitate out the peptides.

6) After purification by Prep-HPLC, Check the Molecular Weight by LC/MSand Lyophilize to Obtain the Peptides in a Powder Form.

EXAMPLE 2 Preparation of Pep(CPP)-FITC Conjugate

(1) Preparation of FITC-CPP Conjugate
